Description:A SYSTEM AND METHOD FOR UNLOCKING A VEHICLE
TECHNICAL FIELD
[0001] The present subject matter generally relates to system and method for an automotive technology. More particularly, but not exclusively to a 5 system and method for unlocking a vehicle.
BACKGROUND
[0002] In the realm of automotive technology, ensuring the security of vehicles and facilitating convenient access for authorized users has been a constant challenge. Traditional key-based systems have limitations in terms 10 of security, convenience, and flexibility. As technology advances, there has been a growing demand for more sophisticated solutions that offer enhanced security while accommodating modern user preferences. One technical problem that the claimed invention addresses is the vulnerability of traditional key-based systems to theft and unauthorized access. Conventional keys can 15 be easily duplicated or stolen, leading to potential security breaches and vehicle theft. Additionally, users may face inconvenience if they forget or misplace their keys, leading to difficulties in accessing their vehicles. Another technical challenge is the need to balance security with convenience. While robust security measures are essential to prevent unauthorized access, overly 20 complex systems can frustrate users and impede efficient vehicle usage. There is a need for a solution that seamlessly integrates advanced security features while maintaining user-friendly access mechanisms. Moreover, ensuring the reliability of vehicle unlocking mechanisms, especially in diverse environmental conditions, poses a technical hurdle. Factors such as 25 signal interference, distance limitations, and varying user preferences regarding the proximity of the key to the control unit can impact the effectiveness of traditional remote unlocking systems. Furthermore, addressing emerging threats such as relay attacks and hacking attempts adds complexity to vehicle security systems. Ensuring that communication 30
3
between the user's digital device and the control unit is encrypted and secure is crucial to mitigate the risk of unauthorized access. In addition to security concerns, there is a growing demand for customizable features that cater to individual user preferences. The ability to adjust the proximity distance for unlocking the vehicle and incorporate biometric authentication adds a layer 5 of personalization and enhances the overall user experience. [0003] Conventionally mechanical keys have been the primary method for vehicle access for decades. They typically require physical insertion into the vehicle's lock or ignition switch to unlock or start the vehicle. These systems are prone to theft or loss, as keys can be easily duplicated or stolen. Users 10 may also forget or misplace their keys, leading to inconvenience and potential vehicle lockouts. Additionally, traditional keys do not offer advanced security features such as encryption or biometric authentication, making them susceptible to unauthorized access.
[0004] Conventional systems use a key fob or remote control to wirelessly 15 unlock and lock the vehicle doors. They typically operate via radio frequency signals. While these systems offer convenience, they can be vulnerable to relay attacks, where hackers intercept and amplify the signal between the key fob and the vehicle to gain unauthorized access. Additionally, these systems may have limited range and reliability, especially in areas with signal 20 interference or when the battery in the key fob is low.
[0005] Passive keyless entry systems allow users to unlock and start their vehicles without needing to physically interact with the key fob. The vehicle detects the proximity of the key fob and automatically unlocks the doors or starts the engine when the user approaches. Passive keyless entry systems 25 can also be vulnerable to relay attacks if the signals between the key fob and the vehicle are not properly encrypted. Furthermore, the reliance on proximity detection means that the vehicle may unlock unintentionally if the key fob is within range, potentially leading to security risks.
[0006] Immobilizer systems prevent unauthorized starting of the vehicle by 30 requiring a valid key or transponder to be present in the vehicle. While
4
immobilizer systems are effective at preventing vehicle theft, they do not address the issue of unauthorized access to the vehicle's interior. Additionally, they may not offer customizable features or advanced security measures such as biometric authentication. [0007] Conventional methods involve biometric authentication systems 5 which uses unique biological characteristics, such as fingerprints or facial recognition, to verify the identity of the user before granting access to the vehicle. While biometric authentication enhances security, it may not be foolproof and can be susceptible to spoofing or false acceptance. Additionally, integrating biometric sensors into vehicles can be costly and 10 may not be widely adopted in all vehicle models.
[0008] Thus, there is a need in the art for a method and a system for unlocking the vehicle which addresses at least the aforementioned problems and other problems of known art.
[0009] Further limitations and disadvantages of conventional and traditional 15 approaches will become apparent to one of skill in the art, through comparison of described systems with some aspects of the present disclosure, as set forth in the remainder of the present application and with reference to the drawings.

[00028] Figure 1 exemplarily illustrates an environmental diagram in accordance with an embodiment of the present disclosure. The present disclosure is a system for unlocking a vehicle (100) which comprises of at least one control unit (104), a user digital device (102), at least one security unit (106), at least one starter unit (108) and a power unit (110). The user 5 digital device (102) configured to send a lock-unlock signal. The least one security unit (106), being in communication with the at least one control unit (104)and the user digital device (102). In this embodiment, the security unit(106)is designed to interface with the user digital device (102) to receive thelock-unlock signal, this involves the implementation of communication 10 protocols and hardware interfaces within the security unit (106) to establish a connection with the user digital device (102). For example, the security unit (106)may include Bluetooth or Wi-Fi modules capable of wirelesslyreceiving signals from the user digital device (102). Upon receiving the lock-unlock signal, the security unit (106) processes the signal to initiate the 15 unlocking mechanism of the vehicle (100). Furthermore, the security unit (106)is configured to send a mobilization-immobilization signal to at leastone control unit (104) based on the lock-unlock signal. This communicationpathway involves establishing a connection between the security unit (106)and the control unit (104) within the vehicle’s electronic system. Once the 20 lock-unlock signal is received and validated, the security unit (106) generates a mobilization or immobilization signal, depending on the user's action, and transmits it to the control unit (104). The control unit (104), in turn, communicate with the starter unit (108), which is responsible for enabling or disabling the power unit (110) of the vehicle (100), such as the engine. The 25 control unit (104) further facilitates the transmission of the mobilization-immobilization signal to the starter unit (108) based on the lock-unlock signal received from the user digital device (102). Additionally, the control unit (104)ensures that the user digital device (102) is within a predefined distancefrom the control unit (104) before processing the lock-unlock signal. This 30 functionality may involve incorporating proximity sensors or signal strength measurements to determine the distance between the user digital device (102)
10
and the control unit. If the lock-unlock signal is received beyond the predefined distance, it is disregarded to prevent unauthorized access. In an embodiment the predefined distance parameter is configurable by the user of the vehicle (100), allowing customization based on individual preferences or security requirements. This configurability may be implemented through user 5 settings accessible via the vehicle (100)'s interface or a digital device application. Additionally, the plurality of predefined distances may vary depending on factors such as the proximity of the vehicle (100) to the user digital device (102), ensuring flexibility in the system's operation. The plurality of predefined distances can be provided on the user digital device 10 (102), either as a set of preset distances or a custom range specified by the user. This information may be stored within the mobile app or settings interface of the user digital device (102), allowing users to adjust the distance parameters according to their preferences or specific use cases. In an embodiment the security unit (106) serves as an immobilizer unit, responsible 15 for implementing security measures to prevent unauthorized access and theft of the vehicle (100). This includes functionalities such as receiving signals from the user digital device (102), validating user authentication, and controlling the mobilization-immobilization of the vehicle (100)'s power unit (110) based on the lock-unlock signal received. 20
[00029] Figure 2 exemplarily illustrates a flowchart of method of vehicle (100)unlocking in accordance with an embodiment of the present disclosure.The method starts at step 200 and proceeds to step 202 where the security unit(106) verifies whether a lock-unlock signal is available from a user digital 25 device (102). If the unlock signal is not available, the step proceeds from 202 to 204 where the vehicle (100) remain in locked condition. The step proceeds from 202 to 204 when an unlock signal is available from the user digital device (102), where the control unit (104) determines whether the user digital device (102) is within a predefined distance. If the vehicle (100) is not within 30 the predefined distance, then the flows back to 204 from 206. The step proceeds from 206 to 208 when the unlock signal from the user digital device
11
(102)is available from the predefined distance, and mobilization-immobilization signal is sent from the security unit. The step then proceedsto 210 where the mobilization-immobilization signal from the security unit(106)is transmitted by the control unit (104) to a starter unit (108). The stepthen proceeds to 212 where the starter unit (108) enables or disables a power5 unit (110) of the vehicle (100) based on the mobilization-immobilizationsignal.[00030] In this embodiment, the vehicle (100)'s security system is equipped with a mechanism to determine the distance between the user digital device (102) and the vehicle (100) itself. This distance measurement can be achieved 10 through various means, including signal strength analysis, GPS positioning, or triangulation techniques. When the vehicle's security system receives a lock-unlock signal from the user digital device (102), it also evaluates the distance at which the signal was transmitted. If the distance exceeds a predefined threshold, indicating that the user is far away from the vehicle 15 (100), the security system disregards the signal.
[00031] In an embodiment, users have the capability to configure the predefined distance for the lock-unlock signal reception. This configurable distance allows users to adjust the security settings of the vehicle (100) based on their preferences or specific security requirements. In this embodiment, 20 users are granted the flexibility to fine-tune the reception parameters of their vehicle (100)'s security system by configuring the predefined distance for lock-unlock signal reception. This feature provides the users to tailor the security settings of their vehicle (100) according to their specific needs, preferences, and security concerns. For instance, users operating in high-risk 25 environments may opt for a shorter distance threshold to ensure tighter control over access, while those in more controlled settings might extend the distance threshold for added convenience. By allowing users to customize the reception distance, the embodiment not only enhances security but also provides a personalized user experience, reflecting the evolving landscape of 30 modern vehicle (100) security where user empowerment and customization are paramount.
12
[00032] In an embodiment, users can adjust the predefined distance using their user digital device (102), such as a smartphone or key fob, according to their preferences or security needs. This adjustment can be made through a dedicated digital device application or interface provided by the vehicle (100) manufacturer. Additionally, to enhance security, the lock-unlock signal is 5 encrypted, preventing unauthorized access or interception of the signal. In an embodiment, the security unit (106) incorporates biometric authentication methods to verify the identity of the user. This ensures that only authorized individuals can unlock the vehicle (100). In an embodiment, the mobilization-immobilization signal sent by the security unit (106) includes a unique 10 identifier for the vehicle (100), preventing replay attacks where intercepted signals are replayed to gain unauthorized access. Additionally, the control unit (104) communicates with the user digital device (102) to provide feedback on the locking or unlocking status of the vehicle (100), ensuring users are informed of the security status in real-time. 15
[00033] The present disclosure can be further clarified by providing a working example of the claimed invention. Let's consider a scenario where a vehicle owner, Sarah, utilizes the claimed subject matter to unlock her vehicle using her smartphone as the user digital device. The system is configured with specific values and parameters to ensure secure and convenient vehicle 20 access. Sarah installs the mobile application associated with the vehicle unlocking system on her smartphone. During setup, Sarah configures the proximity settings, defining a pre-defined distance range within which the lock-unlock signals are recognized. She sets the range to 5 meters for her convenience. Sarah then approaches her vehicle, carrying her smartphone 25 with the mobile application activated. When Sarah is within 5 meters of her vehicle, the system detects her smartphone's presence and verifies its identity. Sarah uses the mobile application to send a lock-unlock signal, indicating her intention to unlock the vehicle. The security unit, which is an immobilizer unit, receives the lock-unlock signal from Sarah's smartphone and verifies 30 that it is within the pre-defined distance range. Upon successful verification, the immobilizer unit sends a mobilization-immobilization signal to the
13
vehicle control unit. The vehicle control unit, which is integrated with the immobilizer unit, receives the mobilization-immobilization signal and transmits it to the starter unit. The starter unit, upon receiving the signal, enables the power unit of the vehicle, allowing Sarah to start the engine and unlock the doors. 5 [00034] If an unauthorized individual attempts to unlock the vehicle using a different smartphone or device, the system will not recognize the signal if it is beyond the pre-defined distance range set by Sarah. Even if the unauthorized individual manages to intercept the signal, the mobilization-immobilization signal includes a unique identifier for the vehicle, preventing 10 relay attacks and unauthorized access. Throughout the locking and unlocking process, the vehicle control unit communicates with Sarah's smartphone to provide real-time feedback on the status of the vehicle. Sarah receives notifications on her smartphone confirming that the vehicle has been successfully unlocked, enhancing transparency and user confidence in the 15 system. Optionally, the system can integrate biometric authentication methods, such as fingerprint or facial recognition, to further verify Sarah's identity before unlocking the vehicle. Additionally, the lock-unlock signals exchanged between Sarah's smartphone and the vehicle system are encrypted, ensuring secure communication, and preventing unauthorized access or 20 tampering. In this example, the claimed invention provides Sarah with a secure, convenient, and customizable vehicle unlocking solution. By incorporating specific values and parameters, such as the pre-defined distance range and optional biometric authentication, the system ensures robust security measures while offering a seamless user experience. 25
